I have had mine for about 4 months now. I have acne on my chin area which I never had before and brown, stringy discharge (TMI- I know).. It doesn't have a smell thank goodness, but I have noticed that I have developed a slight body odor. I am a clean person, but I cannot find a deodorant that works now. Is this a side effect? Does anyone else have this problem? My husband says he hasn't noticed anything, but I have. Oh and headaches, lower abdominal pain, lumpy, tender breasts. I am lucky and I have GREAT insurance with BCBS and paid only $25 for mine so it's no big deal for me to have it removed, but I hate to- I love that I do not have to think about birth control everyday.
